Inheritance diagram for esphome::micro_wake_word::VADModel:

Public Member Functions
	VADModel (const uint8_t *model_start, uint8_t default_probability_cutoff, size_t sliding_window_size, size_t tensor_arena_size)

void	log_model_config () override

DetectionEvent	determine_detected () override
	Checks for voice activity by comparing the max probability in the sliding window with the probability cutoff.

Public Member Functions inherited from esphome::micro_wake_word::StreamingModel
bool	perform_streaming_inference (const int8_t features[PREPROCESSOR_FEATURE_SIZE])

void	reset_probabilities ()
	Sets all recent_streaming_probabilities to 0 and resets the ignore window count.

void	unload_model ()
	Destroys the TFLite interpreter and frees the tensor and variable arenas' memory.

virtual void	enable ()
	Enable the model. The next performing_streaming_inference call will load it.

virtual void	disable ()
	Disable the model. The next performing_streaming_inference call will unload it.

bool	is_enabled () const
	Return true if the model is enabled.

bool	get_unprocessed_probability_status () const

uint8_t	get_default_probability_cutoff () const

uint8_t	get_probability_cutoff () const

void	set_probability_cutoff (uint8_t probability_cutoff)

Additional Inherited Members
